EDAM-4251A
10 DI
, 4 DO and 2 Counter chs DIO Module
The EDAM-4251A is a high-density I/O module built-in two port(RJ-45) 10/100 based-T interface for seamless
Ethernet connectivity. It provides
10 digital input(
Wet contact
), 4 digital output, and 2 counter
channels with
3750VRMS Isolating protection. All of the Digital Input channels support input latch function for important signal
handling. Mean while, these DI channels allow to be used as 300Hz(DI0~9)/4.5KHz(C0~C1) counter. Opposite to the
intelligent DI functions, the EDAM-4251A Digital Output channels also support pulse output function,
Auto-Off Time
of digital output
and
DIO Synchronization
function.
